While your small blodziņš or e-shop slowly mark the interent open country with its three hundred visitors a day is not something to worry about. But if thy MySQL server has its own a few hundred requests per second, many of which are not optimized for various conditions coincidence, it is worth to start thinking. Attempt to dig all the different qualifications and different people in a decade to write the code? Or maybe still cling to the file from the other end?
MySQL is a host of configuration parameters by which the server depending on the type of use can be achieved tremendous growth surge. telekurye Especially when it comes to InnoDB. If you are seriously going at it have been run, it will only invest in research work. Methodology, of course, is very long and wide the story, in turn, analysis and maintenance of the server is available in quite a lot of good tools.
In my opinion one of the best tools is always a good book. And MySQL is the world's best book High Performance MySQL (currently second edition). If you have so far seemed to be that MySQL is a small fignja who turns out there somewhere and not be supervised, then this book is for ikurāt such as you. I own it is decorated with a multitude of grāmatzīmītēm and the thumb on a regular basis.
MySQL Enterprise. Very expensive service of MySQL AB, which is free of charge technical (and not only) also includes telekurye support for MySQL Enterprise Monitor, an excellent part of the MySQL Query Analyzer and MySQL Enterpsise Advisors. The first tool is very good for the overall database load analysis by studying individual applications or groups. Second, in turn, give advice on possible deficiencies in MySQL or the server telekurye configuration tips - how and what needs to be changed so that everything would be fine. All this is included in MySQL Enterprise service, which is priced starting from 2 thousand dollars a year. It's a fact - this is the highest quality tools available.
By the way, I think one of the main plus is that, unlike MySQL Proxy (although the solution is actually the same thing), this product is completely transparent agent. Ie - all the IP-based approach remains valid and should not be changed to @ localhost.
Kontrollbase - free alternative to the above. The project is relatively green, pretty bugains, but quickly gaining popularity and maturity also comes up with it all. Members' ambitions are quite serious, because it looks like they're more or less aiming to previous product "Ficamos." I tried and I think next six months will do it again.
Quite fresh, but the original server numeric data playback tool is mycheckpoint. This principle is one of the most poor Paitone script, which offers an opportunity to generate a lot of different statistics. In a way, to draw a parallel with a bit more modern MRTG (no, did not prevent the use MRTG: P). Development is quite active as a result of the project received serious shape and seems to be apsavesties also a monitoring tool options.
Very old, but still without a little or a must-have tool is a perl written mysqlreport. This makes a simple but very useful work - MySQL status values transformed human easily understandable format.
Purely from the perspective tool everyone should know maatkit. This is a set of perl scripts which are oriented NEBA either a simple user. They can do the same Velli. For this power can be sure, looked at alone tool - mk-query-digest that allows you to analyze not only the MySQL windows, but even tcpdump data collected.
MySQL server deeper improvement certainly come in handy Lab developed by Percona Patches (patches), which, by the way, yesterday was officially put up the MySQL 5.1 series. Well, and, of course, Gugl have their own tools and Patches MySQL server (currently only 4.x and version 5.0.37).
Do not know how to stress this enough, that before telekurye to get on your server, superficial enough to pass through the networks telekurye of information found. One configuration parameter affects ten other - especially those that are InnoDB. In order to successfully operate with analysis and tackle improvements are also necessary to understand what is going on beyond the obvious. So to speak - of the problem.
Not always enough to throw in a server with memory, faster disks and more processors telekurye (in the case of MySQL is a separate story). For example, the authoritative sources have read of cases where even a doubling of memory has led to the opposite effect - the server has become slower. These are the 25 comments (add your own)
